Consequences of complete blockage of the left bundle branch leg

The heart is a unique organ that guides itself, that is, has automaticity, but, of course, taking into account the needs of the body and not without interference in the work of the nervous and endocrine systems. This organ is not just a muscle bag, which is a pump for pumping blood, the heart is much more complicated than it might seem.

The structure of the heart and the consequent causes of blockades

In addition to the musculature, four cavities, valves, own coronary vessels, it has a conducting system and its two centers (the pacemaker). From the main center (the driver of the rhythm of the first order), the electric impulses fall into the second, and then along the left and right leg of the bundle of the Hyis extend to the entire myocardium, which then contracts (and pushes the blood out of the heart).

Naturally, if there is a blockade, in this case a complete blockade of the left leg of the bundle , the pulse, therefore the impulse can not spread further, and this leads to a disruption in the rhythm and, in general, the work of the whole heart. The reason for this may be myocardial infarction, it should be assumed first of all if the blockade occurred for the first time. Other causes: cardiosclerosis, cardiac dystrophy, hypertension, cardiomyopathy, myocarditis, etc.

Consequences of the blockade

A complete blockade of the left leg of the bundle of His leads to a violation of the electric pulse to the left ventricle. But even despite the complete blockade, the impulse nevertheless passes, but bypassing the pathways (anastomoses), and with a delay.

What is the danger of a complete blockade of the left leg of the bundle of His?

Even a complete blockage of the bundle of the bundle can not be asymptomatic, and at first it does not pose a serious danger to life. However, over time, the condition is aggravated, ventricular arrhythmia develops, more often one of its types is ventricular paroxysmal tachycardia. It is she who ultimately leads to fibrillation of the ventricles: a disorderly contraction of myocardial muscle fibers, which is incompatible with life and inevitably leads to death.

Treatment

There is no specific treatment for blockade. With this pathology treatment is aimed at eliminating the underlying disease, which was the reason for the blockade. As a rule, cardiac glycosides, nitrates, drugs that lower blood pressure are prescribed. If the heart rate does not recover, then they resort to an operative intervention: a pacemaker.

Rehabilitation for arrhythmia of the heart

In addition to drug therapy of the underlying disease causing blockade, additional non-pharmacological methods should be included in the treatment, which relate more to rehabilitative measures. In general, this tactic is suitable for other causes of blockade of the left ventricle of the heart . For example, exercise therapy. Physical exercises tonify not only the whole body, but especially fruitfully affect the cardiovascular system, increasing the flow of oxygen and, on the whole, reducing the mechanical stress on the heart. Simply put, moving, we help the heart to disperse blood. Of course, strength exercises are not suitable here. Choice: walking and jogging. But in physical therapy it is very important, especially with heart diseases, so that the load is dosed and adequate to the possibilities of the heart. Otherwise, you can get a negative effect.
